1. Technical Field
The present invention relates to an electronic apparatus, a method, and a computer-readable medium for receiving and reproducing broadcast programs and contents on networks.
2. Related Art
In the past, electronic apparatuses such as a television apparatus receive broadcast signals of terrestrial broadcasting, cable television broadcasting, and satellite broadcasting, and allow users to view broadcast programs. The broadcast programs are previously scheduled to be broadcasted in predetermined time slots. So when users want to view broadcast programs, they must view the programs in broadcast time slots of the broadcast programs or set recording reservation of the broadcast programs.
Meanwhile, as a broadcast environment has developed recently, services that allow users to view contents corresponding to program contents of broadcast programs through a network such as the Internet have come into use. Most of the services employ a so-called video on demand (VOD) system. Users can view contents anytime they want without being bound by broadcast time slots.
However, there are various ways of obtaining contents that can be viewed with the VOD, so users must search the plurality of ways of obtaining desired contents. Furthermore, users can refer to electronic program guides (EPGs) obtained by electronic apparatuses through broadcast waves or through a network, select desired broadcast programs, and confirm their schedules. However, the users cannot obtain from the EPGs whether they can view contents corresponding to the program contents of the broadcast programs through the Internet with VOD. So, the users are forced to execute troublesome, additional search for contents of VOD by using, for example, search engines on the Internet.
Japanese Patent Application JP 2003-125305 describes a television receiver capable of obtaining a program title and uniform resource locator (URL) referring to program information in an electronic program guide to a hard disk recorder connected to the television apparatus while viewing a broadcast program, searching the Internet using a personal computer for program auxiliary information on the broadcast program based on the program title and the URL, and displaying the program auxiliary information.
However, in the television receiver described in JP 2003-125305, the information retrieved from the Internet and displayed on the personal computer is merely auxiliary information regarding the broadcast program such as, for example, comments on the broadcast program and information on a cast, but information regarding a content on the Internet corresponding to the program content of the broadcast program is never displayed. Thus, users are still bound by broadcast schedules to view broadcast programs, and are forced to execute troublesome search operations to confirm whether a content corresponding to the program content of the broadcast program exists on the Internet.
In view of the above, an electronic apparatus, a method, and a computer-readable medium are provided that can allow a user to select and view one of a broadcast program and a content on a network according to the user's preference.

Accordingly, the following detailed description does not limit the invention. Instead, the proper scope of the invention is defined by the appended claims.
As shown in
Recording/reproducing apparatus 100 can includes a digital tuner 1, a demodulator 2, a demultiplexer 3, a codec 4, a recording/reproducing unit 5, a hard disk drive (HDD) 8, an optical disk drive 9, a communication unit 11, a central processing unit (CPU) 12, a read only memory (ROM) 13, a random access memory (RAM) 14, an operation input unit 15, a graphic control unit 16, a video digital/analog (D/A) converter 17, and an audio digital/analog (D/A) converter 18.
Digital tuner 1 may be controlled by CPU 12 to select a specific channel of digital broadcasting via an antenna (not shown) and to receive a broadcast signal including a broadcast program data. The broadcast signal may be, but not limited to, an MPEG stream encoded in, for example, an MPEG-2 TS format. Demodulator 2 may demodulate the modulated broadcast signal.
Demultiplexer 3 may separate the multiplexed broadcast signal into a video signal and an audio signal. Codec 4 may decode the compressed video signal and audio signal separated by demultiplexer 3. Further, codec 4 may transcode, depending on an output target of each of the video signal and the audio signal, a format of each signal to a different format.
Recording/reproducing unit 5 may include a recording unit 6 and a reproduction unit 7. Recording unit 6 may receive as input and temporarily store the video signal and audio signal decoded by codec 4, and output the signals to HDD 8 and optical disc drive 9 to cause them to record the signals while controlling a timing and a data amount. Reproduction unit 7 may read out the video signal and audio signal of a content recorded in HDD 8 and optical disk drive 9, and output the signals to codec 4 to cause codec 4 to reproduce the signals while controlling the timing and the data amount.
HDD 8 may store, in a built-in hard disk, a broadcast program data (hereinafter referred to as program content) received via digital tuner 1 and various contents including a video content of the VOD (hereinafter referred to as VOD content) provided by content servers 23 on Internet 21, various video contents, static image contents, and music contents input from a digital camera or other recording media via various interfaces (not shown). HDD 8 may further store various programs of an operating system (OS), applications, and other data. HDD 8 may record a title list in which the program content and VOD content denoted by respective titles are listed such that the contents can be reproduced. In a case where the stored data are reproduced, HDD 8 may read the data from the hard disk to output the data to recording/reproducing unit 5.
Optical disk drive 9 can be mounted with optical disk 10, and, similar to HDD 8, can record the various data including the program content on optical disc 10 and read out the recorded data. Examples of optical disk 10 may include DVDs (DVD-Video, DVD-RAM, DVD-R, DVD-RW, DVD+R, DVD+RW, etc.), a Blu-ray disc (BD), and a compact disc (CD).
Communication unit 11 may be connected to Internet 21 and serve as a network interface for exchanging the various data with search server 22 and content server 23 based on a protocol such as TCP/IP (Transmission Control Protocol/Internet Protocol).
CPU 12 may access RAM 14 and other components when necessary and may integrally control each component in recording/reproducing apparatus 100. CPU 12 may controls, for example, data recording/reproducing processing by recording/reproducing unit 5 and VOD content search processing using search server 22. Further, the broadcast signal contains a service information (SI) signal for transmitting the EPG data. CPU 12 may control a processing for extracting the EPG data from the SI signal to create an EPG database, and for causing television apparatus 20 to display the EPG data. Reproduction/recording apparatus 100 may obtain the EPG data from Internet 21 via communication unit 11 instead of obtaining from the broadcast signal received by digital tuner 1.
ROM 13 is a nonvolatile memory in which an OS to be executed by CPU 12 and firmware such as a program and various parameters are fixedly stored. RAM 14 may be used as a working area of CPU 12, and is a memory for temporarily retaining an OS, a program, a processing data, etc. RAM 14 may store the EPG database created by CPU 12 and a VOD content database associated with the EPG database.
Operation input unit 15 may receive various setting values and commands as input from a remote controller (not shown) having a plurality of keys operated by a user and output the values and commands to CPU 12. As an alternative to operation input unit 15 being operated by the remote controller, operation input unit 15 may be configured by a keyboard or a mouse connected to recording/reproducing apparatus 100 or a switch mounted to recording/reproducing apparatus 100.
Graphic control unit 16 may execute a graphic processing such as an on screen display (OSD) processing with respect to the video signal output by codec 4 and the EPG data output by CPU 12 to generate a video signal to be displayed on television apparatus 20.
Video D/A converter 17 may convert the digital video signal input from graphic control unit 16 to an analog video signal to output the signal to television apparatus 20.
Audio D/A converter 18 may convert the digital audio signal input from codec 4 into an analog audio signal to output the signal to television apparatus 20.
Television apparatus 20 may display the analog video signal on a display unit and output the analog audio signal from a speaker (not shown).
Search server 22 may search contents servers 23 on Internet 21 for a VOD content in response to a request from CPU 12, and notify recording/reproducing apparatus 100 of the search result. Examples of search server 22 may include a server providing a video search application program interface (API) published on Internet 21. Each content server 23 may be a server storing a VOD content and distributes the VOD content via streaming in response to a request by recording/reproduction apparatus 100.
As shown in
Specifically, CPU 12 may create a search query based on conditions including a title, an episode name, and a broadcast time period (runtime) of each program content in EPG database 31, transmit the query to search server 22 on Internet 21, obtain a search result based on an XML (eXtensible Markup Language) from search server 22 using HTTP (HyperText Transfer Protocol), and create VOD content database 32 for each VOD content corresponding to each program content. VOD content database 32 may be described with an obtainable site (URL) and reproduction conditions including runtime, price type, good/poor image quality, bit rate, distribution period, and presence/absence of advertisements, for each VOD content corresponding to each program content. For example, regarding Program A in EPG database 31, three VOD contents whose obtainable sites (distributors) and reproduction conditions are different from one another may be retrieved. Regarding Program B, two VOD contents whose obtainable sites and reproduction conditions are different from each other may be retrieved. EPG database 31 and VOD content database 32 may be stored, for example, in RAM 14.
Furthermore, when the VOD content is searched for, it is possible to input a search condition conforming to a user's preference.
Referring to
The genre selection using setup screen 35 may be executed for each genre information on each program content included in EPG database 31. As such, when a VOD content corresponding to a program content described as being of movie genre in EPG database 31 is searched for, the search is executed in accordance with each filter of the movie genre on setup screen 35.
As shown in
As shown in
Furthermore, each title field 51 may display a VOD icon 52 based on VOD content database 32, identifying that a VOD content corresponding to the program content can be broadcasted via Internet 21.
As shown in
If the corresponding VOD content exists (Yes), then CPU 12 may judge whether the runtime of the program content is in a distribution period of the VOD content (Step 64). If the runtime of the program content is in the distribution period of the VOD content (Yes), then as shown in
Where “Play VOD” is selected on function list 54 (Yes in Step 67), as shown with arrow (1) of
Furthermore, where “VOD list” is selected in function list 54 (Yes in Step 68), as shown with arrow (2) of
Where there is a VOD content displayed in VOD list 55 that cannot be reproduced because of a restricted broadcast period, the VOD content field on VOD list 55 may be displayed in a pale color or an icon indicating that it cannot be reproduced may be displayed to distinguish the VOD content from other VOD contents that can be reproduced.
Where a user operates the remote controller to move cursor 56 on VOD list 55 and select one VOD content (Yes in Step 71), CPU 12 reproduces the selected VOD content (Step 72) via streaming.
Where a VOD content is broadcasted due to a selection of “Play VOD” or “VOD list” on function list 54, CPU 12 may add information regarding the reproduced VOD content to the title list (Step 73).
As shown in
Title list 80 may display a thumbnail image 81 in addition to the title information on each program content and VOD content. For a program content, thumbnail image 81 may be a reduced-size image of an opening frame of the recorded real data. Furthermore, for a VOD content, thumbnail image 81 may be a reduced-size image of an opening frame captured when the VOD content is reproduced. Alternatively, where a thumbnail image exists in content server 23 of the VOD content, such thumbnail image may be downloaded and displayed on title list 80.
Furthermore, when reserving recording of a program content, recording/reproducing apparatus 100 may generate a recording reservation list in HDD 8 independent of title list 80, and delete a program content having been recorded from the recording reservation list to add the program content to title list 80.
By displaying VOD icon 52 to identify that there exists a VOD content corresponding to a program content in EPG 50, a user can view without difficulty the VOD content corresponding to the program content without being bound by a broadcast time slot of the program content. Thus, even if the program content has already been broadcasted, it can be reproduced via streaming using EPG 50 in the past.
Furthermore, by selecting “Play VOD” on function list 54 with the VOD filter set, a VOD content conforming to a user's preference can be automatically searched for and reproduced via streaming.
There may be various ways of obtaining contents that can be viewed with VOD and various service modes, so it may be difficult to select a way and service mode conforming to a user's preference. For example, a television drama program broadcasted on Monday can be viewed in real time with a charge from website A and can be viewed for free with advertisements a day after broadcasting from website B. Furthermore, a content of high image quality can be viewed with a charge from website C, and a content of poor image quality can be viewed for free from website D. As such, there may be diverse viewing conditions. Furthermore, a user's demand may not be uniform. That is, the user's preference may vary depending on genres of contents. For example, the user may want to view a news program for free even with a poor image quality and view a drama program as early as possible even with a charge. Consistent with an embodiment of the present invention, a VOD content conforming to a search condition set by a user can be searched for and can be reproduced without difficulty. So, user-friendliness can be remarkably increased in accordance with a user's preference.
There may be a case where a URL of a VOD content described in title list 80 is changed, a reproduction condition of a VOD content is changed (e.g., free content is now charged), or a VOD content is deleted by content server 23. In such a case, the VOD content in title list 80 can be updated accordingly.
As shown in
Where a VOD content does not exist in the URL (No in Step 92) or where the reproduction condition does not conform with the search condition (No in Step 93), CPU 12 may require search server 22 to search Internet 21 for a VOD content in accordance with the search condition of the VOD filter (Step 94). Where a VOD content conforming to the search condition is retrieved as a result of searching (Yes in Step 95), title list 80 is updated with the retrieved VOD content (Step 96). In other words, information regarding the new URL and reproduction condition of the VOD content is updated, thus causing the new VOD content to be capable of being reproduced.
Accordingly, title list 80 can be updated following a change of URL or reproduction condition of a VOD content. Therefore, a user can repeatedly reproduce a VOD content corresponding to a recorded program content and conforming to the user's preference without recognizing that title list 80 was updated.
Reservation recording of a program content may involve a problem where a user accidentally sets recording reservations of a plurality of program contents to be broadcasted on different channels in the same time slot such that the plurality of program contents are overlapped in time with each other. In such as case, if only the latter recording-reservation-target program content is recorded while canceling the primary recording reservation, then the user may miss a desired program content.
Furthermore, reservation recording has another problem where a program content is not entirely recorded when a broadcast time period of the program content broadcasted in a broadcast time slot before a recording-reservation-target program content is extended and a broadcast time period of the recording-reservation-target program content is extended.
The problems involved in reservation recording discussed above may be solved using the VOD content.
As shown in
If the reservation time slots are overlapped with each other (Yes), CPU 12 may require search server 22 to search for a VOD content corresponding to a program content whose recording reservation was made earlier of the two overlapped program contents in accordance with the VOD filter (Step 103). Where a VOD content conforming to the VOD filter is retrieved as a result of searching (Yes in Step 104), CPU 12 may add the retrieved VOD content to title list 80 (Step 105). Then, CPU 12 may execute recording of a program content whose recording reservation was made later of the two program contents whose recording reservations are overlapped with each other, in accordance with the recording reservation list (Step 107). Furthermore, where a VOD content conforming to the VOD filter is not retrieved (No in Step 104), the recording reservation list is updated with the program content whose recording reservation was made later (Step 106), and executes recording in accordance with the recording reservation list (Step 107).
Where a VOD content corresponding to the program content whose recording reservation is made earlier of the two overlapped program contents is registered in VOD content database 32 in advance, VOD content database 32 may add the VOD content to title list 80 without executing redundant searching.
Overlapped recording reservations may be backed up with a VOD content, and the VOD content may be allowed to be reproduced with title list 80. Therefore, even if broadcast time slots are overlapped with each other, the user does not lose viewing opportunity.
As shown in
If the broadcast time slot of the recording-reservation-target program content has been changed (Yes in Step 112), search server 22 may be required to search for a VOD content corresponding to the program content whose recording reservation was made in accordance with the VOD filter (Step 113). Where a VOD content conforming to the VOD filter is retrieved as a result of searching (Yes in Step 114), CPU 12 may add the retrieved VOD content to title list 80 (Step 115).
Where a broadcast time slot of a recording-reservation-target program content has changed and thus cannot be recorded, the program content is backed up with a VOD content and the VOD content is allowed to be reproduced with title list 80. Therefore, the user does not lose viewing opportunity.
Recording/reproducing apparatus 100 may transmit a search query to search server 22 by using, for example, a video search API on Internet 21 to search Internet 21 for a VOD content. Alternatively, recording/reproducing apparatus 100 may include a built-in search engine and search for a VOD content using the search engine without using search server 22.
As shown in
The display of VOD icon 52 in title field 51 on EPG 50 may indicate that a VOD content corresponding to a program content exists. As an alternative to displaying VOD icon 52, title field 51 may be displayed with an intensifying effect such as highlight display or 3-D display to indicate that a VOD content exists.
A VOD content corresponding to a program content may differ in certain attributes, for example, image quality, sound quality bit rate, amount of advertisement, price, aspect ratio, length, parental rating, censorship, language, etc.
Title list 80 may be updated by confirming a URL and reproduction conditions of a VOD content periodically or every time a user instructs to reproduce a VOD content.
In the above-described embodiments, recording reservation of a program content whose recording reservation was made later of program contents whose recording reservations are overlapped with each other is allowed to be effective, and a program content whose recording reservation was made earlier is substituted by a VOD content. Alternatively, the program content whose recording reservation was made earlier may be allowed to be effective and the program content whose recording reservation was made later may be substituted by a VOD content.
In the above-described embodiments, where recording reservations are overlapped in time with each other or a broadcast time period is extended, a program content is substituted by a VOD content added to title list 80. Alternatively, when setting reservation recording, a VOD content corresponding to a reservation-recording-target program content may always be searched for, and where the VOD content is retrieved, a user may be allowed to select one of the following options: set a recording reservation of the program content or add the VOD content corresponding to the program content to title list 80. Thus, where the user selects to add the VOD content, a storage volume in HDD 8 can be reduced as much as possible.
Where a retrieved VOD content is encoded with a format which, under ordinary circumstances, cannot be decoded with recording/reproducing apparatus 100, before displaying VOD icon 52 on EPG 50, the VOD content may be in advance transcoded by codec 4 to a format which can be decoded.
A program content may be broadcasted through, for example, radio waves or an IP network. Furthermore, a program content may be a video content or an audio content. Where a program content is an audio content, a corresponding content retrieved from a network may be, for example, on-demand listening on the Internet.
The broadcast program may include programs of digital television broadcasting, analog television broadcasting, digital radio (audio) broadcasting, AM (amplitude modulation) radio broadcasting, FM (frequency modulation) radio broadcasting, IP (internet protocol) television broadcasting, and IP radio broadcasting. The electronic apparatus may include any electronic apparatus such as a PC (Personal Computer), a television apparatus, a radio receiver apparatus, a recording/reproducing apparatus such as a personal video recorder (PVR), a mobile phone apparatus, and a game apparatus. The content may include a video content and an audio content provided by VOD. The network may include the Internet, LAN (local area network), and wireless LAN. The first and second reception means may be implemented by multiple pieces of hardware or by a single piece of hardware. The first and second reception means may include, for example, a digital tuner, an analog tuner, and a network interface. The retrieval means may causing another search engine such as a search server existing on the network to execute the retrieving. The identification information may be, for example, an icon showing that the retrieved content exists or may be implemented by displaying a program information field of the broadcast program with intensifying effects such as highlight display or 3-D display.
